I have a script A which calls script B. I wrote a function in script A to be executed when Kill command is issued for script A and I invoke that function using the trap command.The function identifies all child process running under script A (in this case script B) and kills the child process and performs some operation lets say it updates database tables and log files.

when i execute the "kill -15 script_A_pid" the function that i wrote in script A does not run. I think its because script B (child process) is running.

When i provide kill -15 script_b_pid then child process is terminated and the function that i wrote in script A gets executed.

I would like to know how to execute the function that i wrote in my script Aeven when my script B is running. I want to allways kill script A which should take care of killing script B.

How does your trap procedure look like?

Code:

trap 'function name;exit' 15

Something similar but i placed the exit inside the function

trap function_name 15

I wouldn't think that having a child process would suddenly override traps. Could we see what the code for your script actually is?
